Chick Brooders

A chick brooder is a draft-free box with a heat source, a feeder and a waterer, and it has to hold steady heat for about six weeks. Day-old chicks cannot regulate their own temperature (Alabama Extension), so the brooder does the job a hen would. The extension schedule is 95°F at chick level in week 1, then 5°F lower each week down to 70°F (UMaine Extension). Heat and floor space are the two numbers to get right before anything else.

Start with the box

Floor space is where first-timers go wrong. Give each chick 0.5 sq ft until week 4 and 1 sq ft until week 8. Six chicks need 3 sq ft at first and 6 sq ft by week 4. My chick brooder box and kit picks work the math out by chick count and compare a heated kit against a DIY box with a plate, with prices checked 2026-10-09.

Then pick the heat

A heat lamp is the old default, and Alabama Extension lists 125 and 250 W bulbs. A 12 W plate costs about $2 to run for six weeks, against about $46 for a 250 W lamp at the EIA’s 18.16 cents per kWh. The brooder heat plate roundup ranks four plates, turns each maker’s chick count into plates needed by batch size, and covers the hanging rules if you stay with a lamp.

Then watch the chicks, not the thermometer

Huddled chicks are cold, and panting chicks, or chicks wandering off from the heat, are too hot. The chick brooder temperature chart gives the weekly targets, the Purdue ranges around them, why some hatchery charts start hotter than extension, and why a heat plate needs your eyes instead of a thermometer.

Setup basics

Use 2 to 4 inches of pine shavings and skip newspaper, sand, straw and hay. Make the sides 12 to 18 inches high. Start the heat 24 hours before the chicks arrive. Put feed and water at the edge of the warm zone, not under the heat. When the chicks outgrow the box they need a coop, so see the coop kit picks and the winter heating guide before the move lands in cold weather.
